Automating and prescribing data entry in feature class table fields

Can anyone tell me how to do this? To minimize data entry errors, I want to prescribe which community names can go in one field and then have that choice automatically prescribe which zip code(s) can be chosen for a neighboring field.

For the first part of your question, you can create domains. This will give you a dropdown box in your attribute table when you edit.

For the 2nd part, you can install the attribute assistant. Just download this template, attribute assistant is part of it.

Once installed, you can use an expression to setup a rule that will auto fill your other attribute fields.

Thank you! This is just what I needed. I am self-taught on ArcGIS, and work for a 911 center, so I have told myself that I have no time to explore all the resources available from ESRI. Now I will make the time to explore the ArcGIS for Local Government resource.
